Joke - what do you need?

A man in his 80's struggles to get up from the couch, then starts putting on his coat.
His wife, seeing the unexpected behaviour, asks, "where are you going?"
He replies, "I'm going to the Doctor."
"Why are you sick?"
"Nope, I'm going to get me some of that Viagra stuff."
Immediately the wife starts to get out of her rocker and begins to put on her coat.
The old man says, "Where the hell are you going?"
"I'm going to the Doctor, too."
"Why, what do you need?"
"If you're going to start using that rusty old thing, I'm going to get a tetanus shot!"
